synthesis, characterization and antibacterial evaluation of new triazene ligand and its nano complexes of transition metal ion ti(iii), v(iii), cr(iii) based on 6-aminopenicillanic acid

Novel metal nanocomplexes of titanium (iii), vanadium (iii) and chromium (iii) were prepared from ligands derived from 2-aminothiazole and 6-aminopenicillin acid in a neutral medium ph= 7. the ligand was characterized using ftir, 1hnmr, 13cnmr and uv-visible spectroscopy. the complexes were described using ftir, uv-visible spectroscopy, magnetic susceptibility, molar conductivity, x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem).and atomic absorption spectrometry. in addition to studying some of the physical properties of the prepared compounds, the results showed that the functional groups are (-n=n-n-). the functional group of carbonyl (c=o) of β-lactam acts as a bond in a molar ratio with the metal of (1:2) m:l to give octahedral complexes with sp3d2 hybridization. two different types of bacteria were used to test the ligand and complexes’ antibacterial properties excellent inhibitory effect against bacteria (escherichia coli and staphylococcus aureus). was found for the ligand and its complexes.
